Aquatic pollutants produce multiple consequences at organism, population, community and
ecosystem level, affecting organ function, reproductive status, population size, species …

The last 25 years have seen major advances in the field of mammalian genotoxicology,
particularly with the advent of molecular methods, some of which have spilled over into the …

Growing fish in closed water supply installations with a high planting density leads to
accumulation of waste products, turning the habitat into toxic. Growing fish in such an …

When growing fish in high-tech breeding systems, it is exposed to many stress factors. To
reduce stress, we used spore forms of microorganisms—Bacillus subtilis and Bacillus …

The aim of this study was to access the genotoxic potential of Extremoz Lake waters in
Northeastern Brazilian coast, using the Allium cepa system, piscine micronucleus test and …

One of the fundamentals in the ecotoxicological studies is the need of data comparison,
which can be easily reached with the help of a standardized biological model. In this context …

The neutral red lysosomal retention assay (NRR) of the haemocytes, and the
acetylcholinesterase activity (AChE) in the haemolymph, the digestive gland, the gills and …

Assessment of DNA damage is of primary concern when determining the pollution-related
stress in living organisms. To monitor genotoxicity of the freshwater environments we used …

The micronucleus (MN) assay is one of the most widely used genotoxicity biomarkers in
aquatic organisms, providing an efficient measure of chromosomal DNA damage occurring …

The development of methodologies for biomonitoring freshwater ecosystems is of particular
relevance in view of the serious problem of aquatic environmental pollution. The mussel …
